* Replace the inline blend function by #defineBenjamin Poulain2010-02-151-67/+60
| | | | | | Some compilers do not inline the functions, which is a problem because the number of arguments exceed the limit for SSE, and because it is a lot slower for those low level functions.
* Implement the blend functions with SSE2Benjamin Poulain2010-02-121-0/+218
| | | | | | | | | | | | | When available, use SSE2 to blend images, computation is done on 4 pixels at the time instead of 1 with MMX. Performance improvements: - Blending ARGB32 on RGB32/ARGB32, mostly opaque: 188% - Blending ARGB32 on RGB32/ARGB32, no opaque pixels: 180% - Blending ARGB32 on RGB32/ARGB32, with 0.5 opacity: 187% - Blending RGB32 on RGB32/ARGB32, with 0.5 opacity: 206% Reviewed-by: Samuel Rødal
